DESCRIPTION
Demonstration circuit 918 supports members of a
family of 16/14 BIT 130 MSPS ADCs. Each assem-
bly features one of the following devices: LTC2207,
LTC2207-14, LTC2206, LTC2206-14, LTC2205,
LTC2205-14, or LTC2204 high speed, high dynamic
range ADCs.
Other members of this family include the LTC2208
16-Bit 130Msps ADC with LVDS outputs, as well as
the LTC2203 and LTC2202 which are 16-Bit 25Msps
and 10Msps single-ended clock versions. These
7x7mm QFN devices are supported by Demonstra-
tion Circuit 919 (for single-ended clock input).
Several versions of the 918C demo board support-
ing the LTC2207 16-Bit and LTC2207-14 14-Bit se-
ries of A/D converters are listed in Table 1. De-
pending on the required resolution, sample rate and
input frequency, the DC918 is supplied with the ap-
propriate ADC and with an optimized input circuit.
The circuitry on the analog inputs is optimized for
analog input frequencies below 70MHz or from
70MHz to 140MHz. For higher input frequencies,
contact the factory for support.
Design files for this circuit board are available.
